RECEPTACLE Fen LIQUIDS.

Application filed October 19, 1914.

Illinois, have invented certain new and usefful Improvements in Receptacles for Liquids, of which the following is a specification.

This invention relates to improvements in fluid receptacles, and has for its object to provide an improved form of receptacle in which the fluid may be quickly emptied therefrom without trouble, smooth pouring being insured by provision of means to prevent the formation of a partial vacuum in the interior of the can.

Another object is to provide means for supplying air to the interior of the can or receptacle when the same is partially tilted, when the same is fully tilted and during substantially the entire emptying whereby a smooth flow is insured in either or between either position of. the receptacle, this means also being operable to permit exhaust of air from the can or receptacle when the same is being filled.

Still another object is to provide means for partially opening the fluid outlet should it be desired and to uncover or open the air supplying inlets simultaneously with the partial or full opening of the fluid outlet.

Still another object is to provide means to enable the user to seat the closing cap on the flange orneck of the outlet in position for the threads to immediately engage Without preliminary rotation of the cap or closure.

Still another object is to provide an improved form of cap which may be readily sealed or locked to the ordinary handle of the receptacle.

These and other objects will be set forth and made apparent in the following specification and accompanying drawings, in which; 1

Like reference characters refer to like elements throughout the drawings.

In the form shown in Figs. 1 to 7, A designates a fluid receptacle or can of the common rectangular type having the fluid outlet or filler opening 13 surrounded by the neck or flange B threaded for engagement by the usual cap or closure. A collar or flange G is located around and spaced from the neck or flange B and is provided with the spout portion 0, formed therefrom to facilitate pouring of the fluid from the receptacle. The neck or flange B is provided with the outlet aperture 7) preferably located as closely adjacent the spout portion 0 as possible, as indicated in dotted lines in Fig. 2. Dishedbu-t recesses or grooves (Z and c are provided in the space between the flange B and the collar C. Thesedished-out grooves or recesses (Z, c are provided, with apertures therein and securely fixed in these apertures are the air inlet pipes D, E, respectively. These inlet pipes are arranged as clearly shown in dotted lines in Fig. 1, the inlet D extending from groove (5 to a point adjacent the top of the interior of the can or receptacle and opposite the fluid outlet. The other air inlet tubeE extends from the groove or recess e to adjacent the bottom of the receptacle at a point also opposite the .fluid outlet with respectto the vertical. axis of the can or receptaclef Theypurpose of this construction will be explained below.

, A cap or closure, generally indicated by F is threaded to engagethe neck or. flange B and is provided at its lower portion with the peripheral outwardly extending flange G, the external diameter thereof being slightly less than the smallest diameter of the collar C which tapers inwardly from its contact with the receptacle to its uppermost portion, as clearly shown in Fig. 4L, for example. An annular groove or recess is provided in the flange G and a packing ring g is secured to the under-side of flange Gr adjacent its outer periphery. When the cap is screwed down on neck B to closing position, the aperture Z) willbe closed and the packing ring 9 of cork or the like having contacted with the surface of the receptacle between flange or neck B and the collar C, outwardly of the grooves or recesses d, a, leakage of air or fluid under the flange G will be prevented, the natural resiliency of the flange G serving to maintain the packing ring g in closing position. A seccond flange H is secured to the cap F and extends outwardly therefrom, above the flange G and is of suflicient size to slightly project over the collar C when the cap is in closing or approximately in closing position, so that dust and dirt will be prevented from settling in the space between the collar C and flange B. The cap F upwardly of the flange H is crimped or beaded, as indicated by f, thereby providing a groove between the flange H and the bead or crimp f in which is seated a fastening chain K which may be looped around and have its free end attached to the handle a of the receptacle. When the cap is in position, as shown in Fig. 4, the groove or bulge g is located over the recesses or grooves d, e, and permits free admission of air to the inlet tubes when the cap is partially raised.

The flange G is provided with the lug g, projecting outwardly therefrom. This lug is so located with respect to the threads of the cap and outlet cover, that when the lug is placed in alinement with the pouring spout or portion 0 of collar C, the threads will be in engagement and proper rotation of the cap will result in the same being drawn to closing position without preliminary adj usting and manipulation of the cap to secure proper engagement of the thread. This lug g is so arranged and constructed that it will not permit placing of the cap in other than the position stated, since it projects out slightly beyond the top of the collar C so as to prevent screwing downwardly of the cap F when in other than the position stated. When in proper position, however, the drawing down of the cap will, by virtue of the pitch of the thread, cause the lug g to pass beneath the top of the collar C, permitting rotation of the cap to closing position, as shown in Fig. 4. This construction insures proper placing of the cap as stated above. and without preliminary manipulation thereof. When the receptacle contains fluid and it is desired-to pour the same out, the cap F may be rotated to partially open the opening 6 and the can or receptacle tilted, whereupon fluid which may be in the inlet tube D will flow therefrom into the space between the collar C and flange B and flow out the spout portion 0 together with fluid flowing through the aperture 6. As soon .as a slight amount of fluid has poured from the can, the top of inlet tube D will be exposed and air will be admitted therethrough, preventing the formation of a partial vacuum in the can, thereby preventing the bubbling or jerking flow of the fluid as it is poured from the can so that smooth, uninterrupted flow is obtained. As the fluid is gradually poured from the can or receptacle, the latter is tilted more and more until finally the upper end of inlet E will be uncovered and air will be allowed to flow therethrough, supplementing or replacing the air supply of inlet D should that be covered by the fluid, so that in all positions of the can while the same is being emptied, air is supplied to the interior which insures an even and rapid flow of the fluid therefrom during the entire emptying of the can.

Furthermore, as stated above, the air in lets when emptied mingle their contents with those passing through the regular outlet I) so as to concentrate all flow of fluid from the receptacle.

It will be apparent that by the construction of the receptacle outlet and the closure, immediate opening of the air inlets results in the partial opening of the fluid outlet so that air is admitted at all times to the re ceptacle when the same is being emptied.

I may form the flange H of cap F with the loop or apertured lug 72. adapted to lie adjacent the handle a of the receptacle when the cap is in closed position whereby the sealing strip L of metal or the like may be sealed, as shown in Fig. 1, in position engaging the handle (4, lug h to prevent opening or emptying of the receptacle.

In Figs. 8 and 9 I have shown a slight modification, by means of which I am able to dispense with the collar C if so desired. An aperture 0 is provided in the neck C of the outlet and a small recess or cavity is formed back of the said aperture 0 by means of the looped wall. 0', shown in Fig. 9. The air inlet tube J leads therefrom and has one end secured in this cavity con11nunieating with the exterior of the receptacle through the aperture 0. It will be apparent by this construction, as in the case of the other form a slight opening of the outlet aperture 6 by partial unscrewing oi the cover or cap will permit air to flow in through aperture 0 and through inlet tube J.

In Figs. 10 to 15 is shown another form of my invention. In these views L designates a can or receptacle having the outlet Q and apertures Q land Q into the recepta-t cle L for thepurposelmentioned 111' conne'cpassage M therein the samebeing also capa-' ble of use for filling. Extending upwardly from around this opening is the threaded flange or neck N and surrounding the same is the groove 0. Thisgroove is provided with the slot or aperture'O therein. Spaced from and locatedaround the neclcN is the upstanding flange P providedwith a pouring spout P located as shown in the drawings. An air tube Q communicates with the. groove 0 at Q and extends therefrom to a point substantially dian'ietrically opposite thereto in the receptacle L. This tube. Q is provided with the enlarged elbow Q in which is provided an aperture Q and a flange Q, in which is provided an aperture Q see Fig. 11. The flange Q together with the outer wall of the elbow Q constitutes a race or passage fora ballR. Extending downwardly from and communicating with the air tube Q is the tube S. in communication with the receptacle L adjacent the bot tom thereof and alsosubstantially diametrie cally opposed to the dischargeoutlet ot the receptacle. Theapertures Q and Q and ball R are so arranged that whenithe can ispartially tilted ,to pour the contents'thereof from spout P, the ball R will be in thepositionshown infull lines in Fig. 11 and air will; be permitted to flow through tube tion with the embodiment shown in Figsnl to 7, and as the can is substantially halt tilted the ball R, will. roll to the position indicated in dotted lines in Fig. 11 shutting olt aperture Q and when in this position 1111' will be prevented from flowing through aperture Q also fluid will be. prevented from flowing into tube Q while airwill flow itherethrough and through tube S into the bottom oi": the receptacle, as will be obvious. By this construction I eliminate the necessity for two separate tubes as in the case of the form shown in Fig; 1, for example, but attain the same end.

Coacting with the neck N is the cap :1 comprising a threaded depending collar T,

the outwardly extending top Tt'hndthe intermediate outwardly extending flange T to which is attached a packing ring T l Vhen the cap T is in closing position this ring T will. rest on and cover the groove 0, as is shown in Fig; 15. I also provide a packing strip T on the under side of T, this strip contacting with the top of neck N when the cover is in closing position. The wall P is outwardly bent, as indicated at P,

this providing a passage for air to the tube it Q beneath packing ring T" when the cap T is partially unscrewed or raised from closing position as indicated by thearrow in Fig. 15. The aperture N is provided in the wall N for pouring, and it willbe apparent that this will be partially uncovered as the cap is partially raised thereby permitting control of the fluid from the can or reccpta-.

cle L. At the same time, as explained above, as soonga's the cap and packingrlng T 18 raised at all, air may flow through the pas sage formed by the bent portion P of wall P, thereby insuring-smooth flow of the fluid.

The packing ring T fits closely within the wall and also serves to control thexopening or the spout P,1 as will be apparent.

The a erture 10 in roove O aermits the b partial or full emptying thereof and also provides an additional outlet for fluid from the can, since this aperture 0 will be covered byand furnish an outlet for the fluid when the can is tilted,.owingto itslocation adjacentthe spout P. 1

.To provide for instant engagement of the threads of the vcap T and neck N, I provide bosses orflugs U and Von the receptacle and cap, respectively and s. so arranged that alinement of such lugs when the cap is first placed on the neck will insure engagement ofthe respective threads and assist in ready'fasteningoi the cover to the neck. I. also provide the apertured lug 'l on flange T so arranged that when the cover T is in closing position a stripwof sealing metal .W, or the. like, may be passed through the aperture therein and engage the handle L of the receptacle' tojpreivent; wrongful extraction of the contents of others. p p a It will. be obvious thatwhile I have describedand shown my invention withmore the a receptacle by thieves or or less particularity,the same is susceptible of many modifications andchangesand I do not wishto be restrictedto the forinshown and described beyond the pended claims.
